When enabled, it allows the phone to discover like phones on the subnet that are requesting the files that make up the firmware image, and to automatically assemble transfer hierarchies on a per-file basis. The individual files making up the firmware image are retrieved from the TFTP server by only the root phone in the hierarchy, and are then rapidly transferred down the transfer hierarchy to the other phones on the subnet using TCP connections This menu option indicates whether the phone supports peer to peer image distribution. Settings include: • Enabled • Disabled-default 4-36 Cisco Unified IP Phone 7906G and 7911G for Cisco Unified Communications Manager 6.1 OL-14585-01
